Power is considered to be the major limiter to the design of more faster and complex processors in the near future. In order to address this challenge, a combination of process, circuit design and micro-architectural changes are required. Consequently, to focus the optimization efforts in the right direction, the models proposed and studies performed in(More)
—With the emergence of a plethora of embedded and portable applications, energy dissipation has joined throughput, VLSI layout area, and accuracy/precision as a major design constraint. Thus, designers must be concerned with both estimating and optimizing the energy consumption of circuits, architectures, and software. Most of the research in energy(More)
Due to ever increasing number of transistors and decreasing threshold voltages, leakage energy consumption is expected to play a decisive role in the next generation circuits. We believe that software support is a must to exploit available leakage control mechanisms. In this paper, we present and evaluate a compiler-oriented leakage optimization strategy(More)

Widespread brain-derived neurotrophic factor messenger RNA expression has been detected in the region of catecholamine groups of the rat lower brainstem, while few brain-derived neurotrophic factor-immunoreactive cells were found in this area. In the present study, a double-color immunofluorescence technique for brain-derived neurotrophic factor and(More)
An important problem in extracting maximum benefits from an SDRAM-based architecture is to exploit data locality at the page granularity. Frequent switches between data pages can increase memory latency and have an impact on energy consumption. In this paper, we propose a mathematical formulation, using Presburger arithmetic and Ehrhart polynomials to(More)
Java has become a popular choice for implementing various applications that run on mobile and hand-held devices. Optimizing the energy consumption in mobile environments is of critical importance to prolong the battery life. In this work, we propose an object allocation strategy to reduce the energy consumption of Java applications. This object allocation(More)
Energy consumption is a crucial factor in designing battery-operated embedded and mobile systems. The memory system is a major contributor to the system energy in such environments. In order to optimize energy and energy-delay in the memory system, we investigate ways of splitting the instruction cache into several smaller units, each of which is a cache by(More)
Three-dimensional high-resolution imaging methods are important for cellular-level research. Optical coherence microscopy (OCM) is a low-coherence-based interferometry technology for cellular imaging with both high axial and lateral resolution. Using a high-numerical-aperture objective, OCM normally has a shallow depth of field and requires scanning the(More)
